The objectives of this study are to: 1) study the variations
among stands of old-growth Sitka spruce forest located within a relatively
restricted geographical area, 2) determine the relationship between
species distribution, vegetational pattern,...

Western juniper has rapidly expanded into sagebrush steppe communities in
the Intermountain West during the past 120 years. This expansion has occurred
across a wide range of soil types and topographic positions. These plant
communities, however,...
